Better Off Without It

This is a challenge for inpainted images. When something bad -- dust shadows, red eyes, ugly obstructions, etc. -- appears in one of your photos, you can remove that bad thing and replace it with a credible thing that doesn't distract attention from the subject of your photo. General inpainting used to be very difficult, but digital post-processing tools like GREYCstoration and GIMP's "smart-remove-selection" plug-in (both freely available) automate the process, and manual inpainting using "healing" tools and custom brushes is fairly easy.
